The Watertown housing market serves northeast South Dakota's second-largest city — a manufacturing, healthcare, and agricultural hub in Codington County positioned along I-29 between Sioux Falls and the North Dakota border. Median home prices average around $195,000, making Watertown one of the most affordable larger-city markets in the state. The city's economy runs on Watertown Area Health, 3M's Watertown plant, and a concentration of précision agriculture equipment manufacturers, while Prairie Lakes — Lake Kampeska and Lake Pelican — add recreational value and occasional lakefront premium properties to the inventory mix.
